We have a similar issue at my company, so the call to
/opt/rh/devtoolset-X/enable is done in our bashrc files
Then we use CMAKE_<LANG>_COMPILER_VERSION in our cmake file to make sure its
set correctly.

Subject: [CMake] How to specify Redhat Developer Toolset compiler?
My Centos 7.6 machine has CMake 3.13.5 and g++ 4.8.5 installed:
$ /usr/bin/x86_64-redhat-linux-g++ --version
x86_64-redhat-linux-g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)
I have a very simple CMakeLists.txt:
cmake_minimum_required(VERSION 3.5 FATAL_ERROR)
project(hello_world LANGUAGES CXX)
add_executable(hello_world "")
target_sources(hello_world
PRIVATE
main.cpp
Message.hpp
Message.cpp)
I also have Redhat Developer Toolset 7 installed which I can enable in my bash
shell:
$ scl enable devtoolset-7 bash
$ which g++
/opt/rh/devtoolset-7/root/usr/bin/g++
$ g++ --version
g++ (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5)
How can I get CMake to use the later version of g++ instead of 4.8.5?
